松质骨拉伸破坏细观分析

Microanalysis of the Deformation and Damage Formation of Cancellous Bone

在对松质骨力学性能实验及拉伸扫描电镜观察实验的基础上 ,从细观的角度探讨松质骨的变形和破坏现象。在此基础上 ,运用细观力学模型对松质骨压缩及拉伸的力学行为进行了分析 ,得出了弹性模量与相对密度的关系 ,与实验结果基本吻合。

Based on the experimental observation of mechanical properties of cancellous bone from scanning electric mirror by extension,the deformation and the damage of cancellous bone are attentively explored.The mechanical behavior from the tension and the compression of cancellous bone with micro mechanism is analyzed.The relation between the elastic modulo and the relative density is obtained,similar to the experimental result.
